In this CD hovercraft science project, students will construct their own DIY hovercraft.

This simple and creative arts and crafts activity is great for preschoolers or kindergarteners and uses recycled magazines or newspapers.

This classic children's game demonstrates how sound travels through air vs. through a solid.

How does a kazoo, the strings of a guitar, or the speaker of a radio make sound? The purpose of this science fair project is to show how vibration makes sound.

In this Bernoulli's Principle experiment, you'll learn how an increase in the speed of a fluid, like air, decreases pressure.

Science fair project that examines the relationship between the size of a bubble and how quickly it falls. What is the correlation?

Here's a great activity that uses corks and toothpicks to create a fleet of floating boats. Which design makes for the most seaworthy vessel?

Stir up some friendly competition with this tabletop bow and arrow craft!

In this science fair project, students focus sunlight with a magnifying glass and trap shorter waves to melt ice.

In this experiment, students find out what happens when a less-dense fluid interacts with a denser one, replicating the effect of cooler solid rock on magma.

This science fair project idea lets you can create your own Faraday Cage!

This science fair project demonstrates the principles of reflection through simple experiments involving mirrors and light.

Demonstrate how you can make your own compass using a magnetized needle. It also allows you to compare magnetic north and geographic north.

This conservation of energy demonstration shows why the first hill is the highest on a roller coaster. Learn more about potential and kinetic energy!

Science fair project that tests the effects of diluted soap on the size of bubbles blown from the solution. Will dilution cause smaller bubbles?

This awesome diffraction grating experiment puts high school students' applied math skills to the test by having them calculate the wavelength of laser light.

In this activity, your child will learn about a style of gardening that uses moss, also called "kokedama."

Air invisible; it doesn't make sounds; you can't pick it up and throw it. So how do we know it exists? Help your second grade scientist figure it out.

In this science project, the center of gravity is explored.

In this project, waves of vibrations are experimented with using water in glasses.

Demonstrate Newton's laws of motion by examining the relationship between mass, force, and acceleration during free-fall.

Examine whether males or females are more likely to have a higher center of gravity.

Explore how you can achieve magnetic levitation with the Meissner Effect! This cool science project explains formation and applications of a superconductor.

This science fair project investigates which type of light bulbs are the best at producing flattering photographs in both flash and non-flash conditions.
